The two daily tracking polls appear to suggest that Senator McCain has not realized a bounce yet from his convention:
Rasmussen suggests that with leaners, Obama leads McCain 50 to 45. Gallup actually has McCain down one point since his convention began. While they tracked the race before at Obama, 49 to McCain, 43, they now call it Obama, 49 to McCain, 42. That's statistical noise, of course, but I like the tune all-the-same.
